The panel reviewed several verification systems currently used in the United States and other countries. In addition, the panel reviewed the three optional verification procedures considered in detail by the Aerospace Corporation in their report to the USGS.

8. It allows for differing environmental conditions encountered in the Gulf of Mexico and the Pacific Coast offshore areas, but in each case, the Order requires that the structure be designed to withstand the maximum operational and environmental loads expected to be imposed on it.11 It also requires that the adequacy of the design be certified by a registered professional engineer.

Present Industry System of Design and Construction Review The internal design review is conducted by specialists who have taken part in the actual design and construction work. The reviewers determine whether the design and construction meet accepted industry practice, the customers' requirements, and applicable codes, standards and practices.

The DOE is reported to lack sufficient experienced competent personnel. As a result, the DOE cannot provide a strong monitoring activity nor perform an effective updating of regulations that stay abreast of technological advances.

and operational safety of civil aircraft operating in the United States.13 FAA rules and regulations are established after publication in the Federal Register. The technical base for the certification process of FAA is derived from in-house technical personnel and benefits from the expertise of the National Aeronautics and Space Administration (NASA)

The extent of the technical review undertaken through verification would depend on the degree of experience/knowledge of the design and construction procedures proposed and the expected environmental loading. In the Aerospace study, offshore structures are subdivided into six classes, based on combinations of existing, extended, or new technology and known or unknown environments.11*

Ideally, the verification should: 0 Provide the public and the Congress with added assurance that industry development of the DCS is being pursued in an environmentally acceptable manner; 0 Accommodate and encourage new technology, avoiding over-dependence on codes instead of good engineering; 0 Be flexible and adaptable to frontier-area operations; 0 Provide for an appeal route in contested determinations; 0 Avoid introduction of undue delays; 0 Provide for the most effective use of personnel with experience in design, fabrication, and installation of OCS structures; 0 Minimize disruption to the USGS and industry operations; 0 Provide time for the USGS to acquire and train staff; and, 0 Facilitate "phased" implementation.

since much of the U.S. offshore industry has already worked with one or both of these systems in the North Sea.
